I don't think you are not going to be able to work any of them underwater..its not a function of the case, its a function of the screen being capacitive touch...

I have a feeling this is one reason that the "Plus" (audio increase) button on the side of iPhones now works as the "shutter" button.

Isnt perfect, but it works, if you plan to do a lot of underwater picture taking I would recommend getting one of those sweet durable nikons. For shallow water, daily exposure, and pools, lifeproof is awesome. Long term exposure or depth, they seem to be hit or miss... totally a function of how well you put it on and how often you take it off (these kinda things will wear).

My buddy lost his phone, bottom of Annas Pond in Waimea on the big island, 6+ feet deep......6 months later he got a phone call, someone found it.....

My phone, in a pool for about 30 minutes at around 4 ft, got some water in it....not enough to hurt it at all, but I had to take the case off.

On the life proof one? That's kinda important, since I wanna take photos, and possibly video while snorkeling.

You guys do know you can press the side button of your iphones and it takes the pics right?? We have lifeproofs on all our phones and we're around the water everday. The lifeproof iphone5 case is better than the 4/4s.
We've had phones fall 40'from the towers or off of boats and survive bc they were in lifeproof cases.

So I had an amazon gift card, and used it on the lifeproof case and life jacket. Have used it in the pool with the kids a half dozen times or so and haven't had any issues. Was kind of sketched about it, since I can't get insurance on my phone now. But so far, so good. Looking for to end of October so I can try it snorkeling in Maui.
